I can confirm that STR works even when on power. It just spins fans to max. Until now I've shut down machine, but this time I've accidentaly left it alone and it was sleeping when I came back. So I did a test, and, yes, it works.
Here are details from syslog which could clarify something (my comments are in []): Apr 12 11:27:56 satellite gnome-power-manager: (ivoks) Doing nothing because the suspend button has been pressed - [hitting Fn+F3 doesn't suspend computer (worked till now)] Apr 12 11:28:04 satellite gnome-power-manager: (ivoks) Suspending computer because the DBUS method Suspend() was invoked Apr 12 11:28:06 satellite NetworkManager: <information>^IGoing to sleep. ...

[normal stopping of all devices] On resume, everything is ok, but there are some issues in syslog: Apr 12 11:33:35 satellite kernel: [10333.484000] i8042 kbd 00:06: resuming Apr 12 11:33:35 satellite kernel: [10333.484000] pnp: Failed to activate device 00:06.

Also, sometimes (like after this test), ALPS touchpad doesn't have all the functionality (hor. scroll, different movement speed, etc...). After resume, /proc/acpi/thermal_zone/THRM/temperature shows 56C, while before resume it was 43C. So, processor does run as mad for those 5 minutes while "idling", causing spinning of fans. -- Suspend to ram very slow and not reliable on Toshiba U200 https://bugs.launchpad.net/bugs/90771 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
